I just got a hold of an OS 19 MAX Glow engine, brand new. It is very old but has never been used. It has some details I am not familiar with, and would like to get a hold of an instruction manual, at least the part that describes how to set up the exhaust pipe and how to set the carburator. The exploded view would also be helpful.

I have already looked in the OS web page but have not been able to find any references, or any model like it.

Any help to get the information or the manual will be welcome
